My problem

I have two equal in every respect query. But querys speed are very different.
I have looked at fox.wiki, ut thread and other sources to solve this problem.

I know that, rushmore optimization technique cannot optimize the query for some situation.
But my query has very basic structure that is easily parsed by rushmore


Main Table
-----------
Abone : 715.317 records (Abone table has index on ekler and hurun fields)


Child Tables
-----------------------
Hurun : 20 records (Hurun table has index on id field)
Ekler : 16 records (Ekler table has index on id field)


All the fields (abone.hurun, abone.ekler, ekler.id and hurun.id) are int type and indexed
Index collate ise turkish and alt tables has türkish code page. && cpdbf("abone") returns 1254


--------------------------
First query
--------------------------

select * ;
  from abone, ;
       hurun, ;
       ekler ;     
 where abone.hurun  = hurun.id ;
   and abone.ekler  = ekler.id ;
   and hurun.exp like "Aksi%"

Result : selected 309 records in 6.48 seconds


---------------------------
Second query
---------------------------

select * ;
  from abone, ;
       hurun, ;
       ekler ;     
 where abone.hurun  = hurun.id ;
   and abone.ekler  = ekler.id ;
   and ekler.exp like "Arkd%"

Result : Selected 1155 records in 0.03 seconds
